If your home is like a museum, a staid assemblage of fine memories, I suggest you shake things up a bit. If your imagination is filled with tape loops that keep running storylines you've heard a thousand times before, shake things up a bit. If your daily actions are so thoroughly possessed by the anesthetizing demons of habit that you can't recall your last creative innovation, shake things up a bit. On the other hand, there's no need for blame. Don't berate yourself for your sluggishness. It was an inevitable byproduct of your efforts to solidify and stabilize your life. Just slip into a more playful mode and enjoy a bout of experimentation.
